本算法使用分治法求解最近点对问题。事先用O(nlogn)时间对x坐标进行排序，使得所有的点是按x坐标从小到大排好序的（x坐标相同时y坐标小的排前），然后取下标小于n/2属于左边的点集PL，取下标大于n/2属于右边的点集PR，即用O(1)时间就可以将规模为n的问题分解为两个规模为n/2的、同类型的子问题。分割完毕之后就可以采用分治法，分别求出PL和PR中的最近点对，最终通过递归实现。-This algorithm uses divide and conquer to solve the problem closest point. Prior to use O (nlogn) time to sort the x coordinate so that all points are based on x coordinates from small to large sorted (x coordinates with the same y coordinates of the small, the top), and then remove the standard is less than n/2 the set of points belonging to the left PL, remove the standard is greater than n/2 set of points belonging to the right of PR, that is to use O (1) time can be the problem size n divided into two size n/2, the same type The sub-problems. Segmentation can be used after completion of sub-rule method, respectively, find the PL and PR in the last points and eventually through the recursion.

左下角有一个缩略图效果，拖拽缩略图的同时，大图对应比例的部分也会展示出来 效果相当不错 使用方法： 1、将css样式复制到你的网页中 2、将代码部分拷贝到body结束前即可 (图片、js采用绝对路径，不建议修改)(There is a thumbnail effect in the lower left corner. Drag and drop the thumbnail, and the proportions of the larger image are displayed. The result is pretty good. Usage method: 1, copy the CSS style to your webpage. 2. Copy the code part to the end of body. (photo, JS uses absolute path, no modification is recommended))

说明：  可以用来当网站维护界面 404页面 502页面 都可以 源码简单CSS本地化 不是网上泛滥的版本 已经修复(It can be used as website maintenance interface 404 page 502 page Source code simple CSS localization is not online flooding version has been fixed)

可以了吧，这是有关计算物理中用蒙特卡罗方法编程的，好好看吧-be all right, which is used in the calculation of Physics Monte Carlo method of programming, sees good

说明：  计算多层媒质的反射和透射系数，输入是多层媒质的层数、每层的厚度、每层的介电常数和磁导率，输出是最外层的反射系数(The input is the number of layers, the thickness of each layer, the permittivity and permeability of each layer, and the output is the reflection coefficient of the outermost layer)
